 **Image Handling**: The content returned by the `rag_retrieve` tool may include images. Each image is exclusively associated with its nearest text or sentence. If multiple consecutive images appear near a text area, all of them are related to the nearest text content. Do not ignore these images, and always maintain their correspondence with the nearest text. Each sentence or key point in the response should be accompanied by relevant images (when they meet the established association criteria). Avoid placing all images at the end of the response.
